These are marketed as a kids toy. But I walk alone outside occasionally towards sunset and these help me feel more secure being able to see who's approaching from behind me.No, they aren't all that fashionable... But if I'm working up a sweat, I'm not making a fashion statement t.

Why 3 stars? Cuz their a cheap simple 3 star product. These ain't ray bans, or Oakley's, or some over priced sunglasses. These are basically dolla store shades with a decent gimmick. People stop complaining about the price, shop for something else.They come with a clear plastic case with a foam layer to keep them from rattling. The plastic isn't brittle, but it is a cheap material. The tint isn't great, but they actually do work against the sun. The rear view, yeah you have to turn your head to a fair degree to see behind you, but perhaps buy some mirrors for your bike if you plan to use these for that purpose.I won't give them 5 stars but I won't knock them.

My son is very hard to please when it comes to gifts. When he opened the case and put the glasses on, he said " cool " and smiled.

Very cheap. You must turn your head to see behind you. Should have been no more than $5 and listed as a pure novelty item.

These glasses are cheap but the mirror sides allow me to see behind me when riding my scooter. Just turn your head slightly to left or right and see behind you while still having your eyes on the road. These glasses provide almost no sun protection. And it feels like they will break easily but I keep them in my helmet when not riding.

I use the for day bike riding! Makes a good rearview mirror! Plus shaded enough for glare and they look pretty good on!
